Teacher: In this task, you will be presented with a passage and have to answer a question based on your understanding of the events inferred from the passage. Among the entities, try to find the best entity that is most likely to fill in "_" and classify the answers based on options.
Teacher: Now, understand the problem? If you are still confused, see the following example:
For four years we have waited expectantly for the pitter patter of tiny paws. Soon, that wait could finally be over. Tian Tian, the UK's only female giant panda, has conceived and could give birth to a cub as early as August. However Edinburgh Zoo, where the pandas live, have warned people 'not to get too excited' as the process is 'extremely complex'. Moreover, on the two previous occasions keepers inseminated Tian Tian - whose name means 'Sweetie' - she has failed to produce a panda cub. She was artificially inseminated again in March this year, but keepers at the zoo say implantation - when a fertilised egg attaches to the uterus - has not yet occurred.Tian Tian has conceived and could give birth to a cub as early as AugustShe has been inseminated twice before but so far failed to produce a cubTian Tian and Yang Guang arrived in 2011 from China to great fanfareOn loan at £600k a year, became first giant pandas to live in UK for 17 years 
 Questions:Under the terms of the agreement any cubs will return to _ at the age of two, the age at which they would normally leave their mother in the wild. (A) Tian Tian (B) UK (C) Edinburgh Zoo (D) Sweetie (E) Yang Guang (F) China
Solution: (F)
Reason: This is a good example. Based on the passage, any cubs will return to China at the age of two

Now, solve this instance: (CNN) A new study lends support to one of the biggest fears about Zika virus: It might increase the risk of the rare neurological syndrome Guillain-Barre. Years before Zika virus first appeared in Latin America, it spread from Africa and Asia to Pacific islands. From 2013 to 2014, French Polynesia had 32,000 suspected cases of Zika virus. During this same period, there was also an uptick in cases of Guillain-Barre. Researchers in French Polynesia and Europe looked at those 42 cases of Guillain-Barre in the Pacific Island nation between October 2013 and April 2014. They asked whether there was any evidence these patients had been exposed to Zika virus.A study finds evidence that people in French Polynesia affected by Guillain-Barre were exposed to Zika virusResearchers estimate that about 1 in 4,000 Zika infectious could lead to the rare neurological syndromeGuillain-Barre causes muscle weakness and paralysis, and many patients take weeks to months to recover 
 Questions:The researchers estimate, based on the rates of _ and Guillain-Barre in French Polynesia, that one in 4,000 people infected with Zika could develop the neurological syndrome. (A) CNN (B) Zika (C) Guillain (D) Barre (E) Latin America (F) Africa (G) Asia (H) Pacific (I) French Polynesia (J) Europe (K) Pacific Island
